Question

You have a 32-year-old female patient with the following anthropometric measurements:
Weight: 120 lb Height: 5 ft 4 in BMI: 20.6 kg/m2
She has been keeping a diet record, and after analyzing it, you find that her average energy intake for each meal/snack is as follows:
 Breakfast: 500 kcal
 Midmorning snack: 200 kcal
 Lunch: 1000 kcal
 Afternoon snack: 250 kcal
 Dinner: 550 kcal
 Evening snack: 400 kcal
1. Thus, her total energy intake averages _______________ kcal/day.
You calculate her basal energy needs according to the Mifflin-St. Jeor equation and find that her basal energy expenditure (BEE) is 1240.5 kcal/day. She reports a very active lifestyle. Therefore, you multiply her BEE by a physical activity factor of 1.725. Her total energy expenditure is 2140 kcal/day.
2. You explain to your patient that she eats more kilocalories than she is using in a given day, thus she has a positive energy balance of _____________ kcal/day.
Questions for Analysis
3. If she continues to consume and burn the same amount of energy, how long will it take for her to gain a pound of fat? _______________ DAYS
4. How would you recommend that she change her lifestyle to maintain her current weight?

Answer 1

1. SOLUTION Giken - Hage 32 years weight = 1201b = 120X-454= 54.48 kgs Height = 5'4" = Gdl inch = (664.p.sy) cms BMI = 20.6 kg/m2 = 162.56 cms Her daily calory consumphön – Breakfast =500 kcal Morning Snacks = 800 kcal Lunch = levo i cal Afternoon Snack = 250 kcal Dinner = 550 kcal Dinner Snack = 400 kcal So her total energy intake average is 1 500 + 200 Hloro +250 +550 thoro = 2900 kcalfday) Now, the Basal Energy Expenditure can be calculated by Miffling, St, Jeor Equation, that can be given as Į BEE = 9.99% Weight (in kg) + 6.25x Height (uncom) - 4.92 x Age - tee 16)(for females) =(9.99 x54-48446.25X162.5644-92X32)-161 BEE = 1240.54 kcalfday Answer.

As it is also given that her physical activity factor is 1-725 so fer totaal energy expenditume is = 1.725X12.40.54 - 2140k caffetry 6 ster Total Energy Intake is = 25ookcal/day And, Her tobel-emergy Empenditure is 2140 Kcal play so she has a positive energy balance of a Intake – Sxpenditure 2900 – 2140 = 760 K call daya Maswer. ③. As we know that one gram of fert yields 9 Keal so to gain ne pound of fat that is R 1 lb = .454 kg = usu grams so to gain 454 grams of fat she will require 1 454x9 = 4086 kcal because she has a possitive energy balance of 760 kcall day So to gain one pound of fat, she would take = yo so = 5:37 ♡ 6 days Ans.

0.4> To maintin her current weight, - Either she should declense her calory intake or she should burn more calories by increasing physical activity

1. Total average energy intake is 2900 kcal/day
2. BEE = 1240.54 kcal/day Hence Proved
3. Total energy expenditure is 2140 kcal/day
4. Positive energy balance is 760 kcal/day
5. Number of days to gain 1lbs of fat she would take 6 days.
